Factors associated with cognitive function that cause a decline in the level of activities of daily living in Alzheimer's disease.

Visuospatial cognition had an important effect on the decrease in basic ADL and IADL. Furthermore, the subitems with minimal effect on the decrease of basic ADL and IADL differed. Therefore, it appears that specific activities have little effect on the maintenance of ADL and IADL, and that determining residual cognitive function and utilizing this as a means of compensating for decreased ADL is a useful strategy.
